Abstract: Two new species of predominantly Australasian genus Austrelatus Shaverdo et al.,
2023 are described and illustrated: Austrelatus mirai sp. nov. from Selangor
State in Peninsular Malaysia is similar in habitus to the South Indian species
A. boukali (Hendrich & Balke, 1998) and A. davidi (Wewalka, 2017); however,
the shape of the male genitalia suggests that it is closely related to
Austrelatus species from Kalimantan. Austrelatus riberai sp. nov. from Shan
State in Myanmar is most similar to Sino-Japanese A. parallelus (Zimmermann,
1920). Findings of Austrelatus species in continental Southeast Asia fill the
gap in the distribution area of the genus between India, China and Japan on one
side, and the Sunda Islands on the other side.
